  • a In this analysis, as a means of assessing nonproportionality, separate Cox models were constructed to evaluate for short-term and long-term outcomes. Numbers are hazard ratios. Three different definitions were used (18, 36, and 60 months) to assess the effect of the specific definition of short- vs. long-term outcome.
